I serve for the LiFamily and I look after their libary.（serve for--serve,serve是及物的）
Of course my brain is as lager as a mountain （larger——large,但我不確定你是不是打錯了）
Lis has a child who needs me remember all his school textbooks so I can do his homework for him.（needs后面加to）
He just gives me the information on the subject,that has to be done .(that改成which,that不能引導(dǎo)非限定）
Sometimes I didn't think it is right to do his homework for him——it's somewhat cheating.（didn't——doesn't）
下面幾個是我不太確定的
My job is to store all the books which they borrow from their school or friends in my brain.（borrow——borrowed）
Of course my brain is as lager as a mountain so work like that is no trouble to me.（trouble——problem,如果larger真打錯了的話）
就這些了,別的沒看出來,但整篇文章讀來覺得都不順,應(yīng)該還有錯.如果是試卷中的改錯題的話,個人覺得這道題出的很一般~個人水平有限,
